This invention relates to that class of compounds used in lubricating all kinds of rotating or sliding machinery; and it consists in a composition of various ingredients, among which are the following, which, with their proportions, Will now be described.

To prepare the compound for use:

First- Take pulverized hydrochlorate ..of ammonia 26 parts Nitrate potash. 4.0 Li1ne-water.. .445

511 and make them into a solution.

Second- Lard-oil .447 parts Soft Water 27 Cyanide potash 2 Nitrate silver l Spanish whiting l2 Mix the same and set it aside to settle; then pour 011' the top till it runs turbid; then take the two compounds, as above, and pour them into one vessel, and agitate briskly until thoroughly mixed, when a complete admixture is accomplished, holding all the weightier ingredients fully in suspension.

The compound is now ready for use; but to preserve it from deterioration it must be kept in hermetically-sealed vessels.

This compound, although specially designed for a lubricant, is'adapted as a liniment for man and horse.
